The success rate of two groups were 100%, and the mean degree of splenic embolism by SPSE was 82.4% (75%-90%), which close to the extent of expected embolism. The improvement of hemolysis in patients after SPSE was not different from that after total splenectomy, and the effect can be maintained for a long time. The average hemoglobin value increased significantly from 6.97g/dL before SPSE to 12.2g/dL after SPSE (P < 0.001). SPSE was performed without any serious complications. All children suffered mild to moderate postembolization syndrome including pain, fever and vomiting, which could easily be controlled with appropriate supportive therapy.
